Biology paper 61... DONE

[phantom]

You didn't have to write anything for the last. It said state what happens in those which you observed a change.. I just wrote for the first 2.

I wrote no net water movement for the third one, the question was 3 marks.

 

[Jisu]

And for the graph.. what was in the x and y axis?

y was frequency
x was the range of lengths

I wrote enough for 3 marks by explaining the first 2 x)

my bio teacher

Maybe, but I dont think they would cut a mark for using a different unit.

Well so far the only question that I'm 90% sure I lost a mark in is the improve the reliability one.
Shouldn't have written "repeat experiment" :S

aaaaaaahhhhhhhhhh
r u sure??
but watever
i mean ill just lose one mark
plus i mentioned everythin else abt osmosis...

 

[Jisu]

Lets see, actual length = 5mm
Length I measured (in mm) = 71mm

71/5= 14.2

The way I did, actual length = 0.5cm
Length I measured (in cm) = 7.1 cm

7.1/0.5=14.2

I don't think it mattered which unit it was converted into.

exactly

Yeah ahah, don't worry even if you end up getting 30/40 you still have a shot at an A*.
Paper 6 is 30% of the mark x)

yea maybeeeee
did u draw a bar chart or take da frequency density like in math and draw a histogram??

Repeat experiment is ALWAYS used in experiments so it's right even if u didn't have to repeat it.. i answered almost all past papers and they all mentioned REPEAT in all experiments unless they said it in the question.. Even if there was no numbers..

i hope da curve is low this time ;D

 

[ZainH]

yea maybeeeee

Bar chart.

 

[Jisu]

Bar chart.

i shaded it though
cu it wasnt that visible
soooo is it fine?

 

[ZainH]

I hope so.. I shaded it as well lol
Oh and btw since paper 3 is 80 marks, paper 1 is 40 and paper 2 is 40.. the total marks for bio is 160.
Paper 3 is 50% of that, so paper 6 is only 25% of our grade! Thank god x)

What do you mean? sorry i don't take maths this year..

Frequency Density?????????!!!!!! No I didnot use that, I just used Frequency as Y-Axis and Range of lengths/cm in X-Axis

ok
dats wat i did too
just wonderin cuz it said histogram

 

[Addoozz]

yup that's correct

 

[Ahmedboombox]

That histogram question ffs. It was only 1 mark but I think I got it wrong.. I wrote natural selection.
But the answer was "variation among the species caused this type of shape" .. Thats what the smartest girl in my class wrote :S

So she wrote exactly what i wrote mashallah , i just made a mistake in the nematodes part i lost 3 marks in that. The rest was hamdilliah good.
